When we designed this catch we wanted to have the most function options available, the best separation method, and the easiest to service. The Turner engineered catch cans offer a pre-setup design based ion desired flow direction, however, this does not limit you to this flow. The inner baffle orientation can be easily adjusted to flow in both directions in case you decide to move this catch can to a different vehicle. A 4 chamber system baffle system inside the catch can was engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can. Having a closed/recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation.

Turner E9x Cowl Delete Harness Mounting Bracket mounts to factory bolt holes; it is an easy no-drill install that creates a solid location to tie back your engine harness. However, removing the cowl introduces the possibility of dirt and debris entering your cabin. To solve this issue we suggest pairing it with Burger's Cabin/Cowl Delete Filters. These are small, dry, and maintenance-free filters that both add a finished look to your engine bay and prevent debris from entering the cabin.

We know if a soft mount offers a sloppy connection it doesn't work on the track, and a solid mount isn't acceptable as a daily driver (for most!) and set out to engineer a mount that would meet the needs for both. At the core of our enclosed design is a partially-constrained, multi-piece polyurethane bushing with precisely-set preload. This architecture absorbs and disperses resonant engine frequencies as opposed to amplifying them (like some other designs do), which results in a positive-connection, enthusiast-feel mount with the vibration.

The idea of power pulleys is simple. The less effort the engine puts into running accessories such as the water pump, power steering, pump alternator etc., the more of that power can be used elsewhere - your wheels! The way this is done by reducing the rotation of the pulleys by as much as 10-20%! The end result is more horsepower at your disposal. Turner has done extensive testing (on and off the track), to ensure that the accessory systems still function as intended and without failure. These pulleys offer an excellent compromise of power gains, reliability, and performance.

Free additional power to your M3’s rear wheels without sacrificing or compromising your BMW’s reliability. Machined from 6061-T6 aerospace aluminum, Macht Schnell Performance Underdrive Pulleys are strong as well as lightweight to limit parasitic drag from the accessories within a moderate level for maximum performance on or off the track. After machining and engraving, pulleys are then T3 hard anodized for additional strength, anti-corrosion & wear resistance. Our DualDrive design replaces the Crank Accessory & Power Steering Pulleys, resulting in an additional 9-14 HP and 7-9ft. lbs TQ gain for the M3. Gains are due to a reduction in power required to turn accessories; an increase in accessories lifespan due to lower speed will also result. All factory harmonics/balancing are undisturbed. Macht Schnell Performance Underdrive Pulleys have no negative effect on accessory operation and comes fully equipped with new belts. Already have this kit and need new belts? See T#14491 and T#14489 Performance Underdrive Pulleys Features: DualDrive design allows maximum performance, with minor effect on accessory speed Proper cooling temperatures are retained at proper levels on or off the track Maintains proper alternator speed, allowing sustained levels to sensitive control modules Machined from 6061-T6 aerospace aluminum T3 Hard-Anodized for maximum strength and corrosion/wear resistance No affects to crankshaft dampening or harmonics Simple bolt-on installation
